wp-block-hb-message--withicon\"><strong>Note:<\/strong> Siperb is designed for flexibility and may differ from traditional approaches, offering multiple ways to connect to your PBX.<\/p>\n\n\n\n<p>You first need to understand <strong>Registration Modes<\/strong>. There are two supported registration modes, but not all the devices support this. On <strong>Web<\/strong> and <strong>Desktop<\/strong>, you can configure the Softphone to connect directly with your PBX or Voice System (<strong>WebSocket Registration Mode<\/strong>) or via the free provided Siperb Proxy (<strong>Proxy Registration Mode<\/strong>).<\/p>\n\n\n\n<p>Learn more: <a href=\"\/kb\/article\/registration-modes\/\">Registration Modes: Which One is Right for You?<\/a><\/p>\n\n\n\n<p><strong>WebSocket Registration Mode:<\/strong> Your devices connect directly to your PBX using WebSocket. No intermediaries, no proxy. This is the simplest setup if your PBX supports WebSocket and DTLS-SRTP encryption. If you are using the Desktop Application, then you can also enable an additional feature where the transport is opened up to UDP, TCP and TLS, and using these modes, media is also transcoded for you, so you can make and receive calls directly with your PBX or Voice System. This additional feature means that no signalling or media touches our network.<\/p>\n\n\n\n<p><strong>Proxy Registration Mode:<\/strong> Siperb\u2019s proxy sits between your devices and your PBX, adding features like SIP Trace, media transcoding (for legacy PBXs), push notifications, and automatic failover. Ideal if you need more control, diagnostics, or support for older systems. This is also the only option for mobile devices since the mobile device can often switch between GSM and Wifi &#8211; making the connection unreliable. <\/p>\n\n\n\n<p>When using the <strong>Proxy Registration Mode<\/strong>, the softphone is designed to automatically register to the Siperb Network, so this means you are required to create <strong>connections<\/strong> in the Settings section in order to bridge the calls between the Siperb Network and your PBX or Voice Service.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Connection Methods<\/h2>\n\n\n\n<p>Siperb supports multiple ways to connect your PBX:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Outbound Registration:<\/strong> Siperb registers with your PBX on behalf of your users. Most common setup.<\/li>\n\n\n\n<li><strong>Outbound Trunk:<\/strong> Static IP connection for larger deployments or ITSPs.<\/li>\n\n\n\n<li><strong>Inbound Registration:<\/strong> Your PBX registers with Siperb. Useful when your PBX is behind NAT.<\/li>\n<\/ul>\n\n\n\n<p>Learn more: <a href=\"\/kb\/article\/an-introduction-to-connections\/\">An Introduction to Connections<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Getting Started<\/h2>\n\n\n\n<p>New to Siperb?
